Branchus - Trench Warfare - Sabotage

Objective: 

The aim is to escort/protect a demoman for long enough that he/she can reach
the top of the enemys tower and plant a detpak there.

Scoring: 

Upon completion of the objective the Sabotaur will be awarded 10 frags, 
his/her team will be award with 50 points also.

Other Notes: 

Whenever either satelite tower is blown, all players are moved
back to their starting positions. 
There are no limits to the number of demomen that each team can have,
although they will require other classes to protect them as the 
nature of the terrain can cause some nasty unpredictable grenade 
bouncing.
I expect this to be a particularly "bloody and brutal" map, 
especially with a lot of players.
